Specification of Letters Patent.

Patented May 2, 1916.

' 4 u Application filed October 27, 1813. Serial No. 797,591.

7 To all whom it may concern Be it known that I, THoMAs Masonry, a citizen of the United States, residing at Buifalo,'in the county of Erie and State of New York, have invented certain new and useful Im rovements' 'in' Car-Doors, of which the ollowing is a specification.

My invention relates .to improvements in doors for box freight cars; its primary object being the provision of adoor which can be used as an ordinary car door for iackage or bulk frei ht or as a grain car oor, it being partiou arly designed for the latter purpose.

Another object of my invention is to provide a car door and ,improved adjuncts which, when used on cars carrying grain provides for closing of crevices between the door and its frame so as to insure a tight joint and prevent loss of grain by leakage;

Another object of my invention is to provide a car door and adjuncts therefor secured to the body of the car and arranged so that when carrying grain within'the car said adjuncts'may be movedin co-acting relation with the car door, and when carrying packa e' or bulk freight they may be move out o coacting relation with said car door.

Another ob ect of my invention is to so construct the cardoor and its relative parts that all coopering or boarding up of the car door opening, asnow required when transporting grain, may be dis ensed with, thus eliminating the cost of la or'and material required ea htime a car is put'into use in transporting grain, which material is an absolute loss owing to the fact that it cannot again be used for coopering another car.

Another object of my invention is to so construct the car door and its relative parts that the pressure of the grain within the car will cause tight joints to. be made between the door and its co-acting crevice-closing plates.

With these and other objects in view, my invention consists in the novel features of construction, and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined-claims.

In the drawings,--Figure 1 is a side elevation' of a portion of a car equipped with my improved car door audits adjuncts. 'Fig. 2 is an enlarged horizontal section taken on line 2-2, Fig. 1, the car door being entirely closed. Fig. 3 is'a similar section showing the car door slightly open and in position to be moved along its tracks to completely 0 en the door opening. Fig. 4 is an enlarge vertical section taken on line i -4, Fig. 1. Fig. 5 is an enlarged vertical section taken on line 5-5, Fig. 1. Fig. 6'- is an enlarged vertical section taken on line 66, Fig. 2. Fig. 7 is an enlarged vertical section taken on line 77, Fig. 4. Fig. 8 is a face view of a portion of a car showing the face plates of the door frame removed. Fig. 9 is an enlarged horizontal section taken on line 99, Fig. 6. Fig. 10 is an enlarged vertical section taken on line 1010, Fig. 1. Fig. 11 is an enlarged vertical section taken on line 11--11, Fig. 6. Fig. 12 isa vertical section taken on line 12-12, Fig. 10. Fig. 13 is a vertical section through the locking device for the unloading door. Fig. 14 is a plan view of the same.

Referring now to the drawings in detail, like numerals of reference refer to like parts in the several figures.

The reference numeral 15 designates the car; 16 the car-door opening, and 17, 18 the upper and lower tracks, respectively, by means of which the car-door 19 is supported and guided in its movements. These tracks 17, 18 are arranged respectively above and below the car-door o ening and extend 2 distance to one side 0 the same, as is common in freight car construction. As clearly shown in Figs. 2 and 3, each of the track: has a. portion 20 parallel with the side 0' the car, and a portion 21 arranged at slight angle to said parallel portion, th' parallel portions 20 being arranged to on side of the car door opening and the an gular portions 21 being respectively abov and beneath the car-door opening. Thi arrangement of the tracks is not new wit applicant, and is now used on some type of cars for directing the car-door out of th car-door opening and along the side of th car at one side of said opening.

The upper track 17 is supported by am 22 extending from a door cap 23, said tree and the door cap with its arms being s cured in place by screws 24 passed throug the track, the arms and cap and taking ini the upper sill or header of the car-door, best shown in Fig. Said door cap fc lows the lines of the upper track so th it overhangs the car-door in any positi said door may be in, and this cap is pa ticularly desirable when the car-door fits into the door opening as it,serves to;prevent rain, sleet or other elements of the weather reaching the upper edge of the door 'lnd entering the car at this point.

'- The lower track 18 is supported by means of brackets 25 which are held against a rnetallic plate 26 fastened against the side of the car directly beneath the door opening, said brackets having. spacing lugs. 27 projecting from their rear faces so as ;to provide a spacebetween them an d the late .26. The means of securing said rail and rackets in placehbeing best illustrated inolf ig j, wherein screws 29 are shown passing throughthe rail, the bracketand the plate 26 and taking into the lower sill 28 of the car. a

,118 designates thezfloor of the car which slightly, overlaps the sill 28. -From the floor outwardly to the front fa ce of the plate 26 a metallic plate 30 is provided which faces the lower sill and serves'as a door sill. v

31 designates thejambs of the door opening, each beingrabbeted, as at 32, to recei ve the vertical longitudinal marginal, portions ofthe door 19. One ofthe jambshas an angle plate 33 secured thereto, anda, facing plate 34 which overhangs the rabbet-,. 32 thereofi so as to provide a vertical-;pocket;35, and secured to the carat theopposite s de of the door opening is a late 36 having at one edge an outstanding ange,37. Secured to said plate is a facing plate 38 wh1ch is spaced from the plate 36by,the rfiange of the latter so as to provide, a YQltlCill;, gllid6 way or chamber 39. In ,said guideway or chamber .39 a vertically-disposed creviceclosing plate 40 is positioned; said plate being normally fully confined within t he said chamber or guide-way, but when the car is used for transporting grain; it is adapted to be slightly extended eo as to overlap the adjacent vertical marginal. portion of the car door, as;clearly shown iryEig. 2. A second crevice-closing plate-41,is,provided ,at the lower end of thecar door-opening it beingmovably held against the-plate 26 by the brackets 25, saidlast inentioned crevice-closing plate being normallyositioned withits upper edge in line wit or beneath the door sill 30 but beingadapted to be moved upwardly so as to overlap-the lower marginal portion of the car door, as shownin Figs. 5 and 6.

The means of guiding and actuatingthe side crevice-closing plate isbest illustrated in. Figs. 6 and 11, and for the purpose. of

actuatingnsaid plate thetlatter is provided with a. circular opening '42. near its lower end in which is positioned.ameccentrically 1ournaled actuating disk 43, said disklhaving oppositely-disposed stub; Shafts-44,.45,

which are JOUI'DfllEd irespectively-,in ;,the plates 36, 38, the stub shaft being exttt e eirom-tandit terminates in a tended through the plate 38 so as to project square or other non-circular end portion 46 to which --is' adapted to be applied a wrench or other suitable tool for rotating the actuating disk and causing the plate to be moved outward ,or Inward ,u ts receiving chamber.

In cider to permit's'uch movement, the creviceclosing plate is provided with guide slots 47 arranged at intervals in its length, inzwhich slots iantifrictipn rollers; 48 v are. located w hich turn loosely upon pins 49 secured in the plates/ 36,38 so as to, spanthe chamber or guide ,way 39 in vai'liich'tlre, crevice-closing plate is, situated. lVitb a view of causing the plate toinove putwardlyso that first one end over apsfthe ed'acent, edge 0f. the door and the remaining portion of the plate gradually fi llows by a dragging movement, the guidel qts 47: may 'be .irregular. as clearly sl pwn in Fighji. Thdpppermost guide slot being inclined downwardly 'and outwardly with a slight downwarddefleotion 50 at its inner en d,; while the'lowerrn ost guideslot is directed downwardly and outwardly as a at .51 thence upwardl-y. and. outwardly, as at 52 be ngsub stantially of llformation. The second guide slot from the .top. of "the plate isincl ned downwardly and outwardly .with aeslight up ward deflectionfiii, while the third guideslotgjron the top of-the plateis substant ially similar to ,t he lowermost guide slot with the exception .thatlone ar niof the N shaped-slot ,is slightlyi longer than.the th r.-- y .re n; of; th cons r n the lower-end ofitthe creviceclosing plate is carriedputward ,during the initial movement of the eccentric actuating disk, and the remaindem-pfthe plate is gradually carried outwardduring the remainder of the movementipi saiddisk thereby requiring less effort, ,-to ,actuate: the plate than if said plate werecarriedoutward in a straight line, due to theadiminished .friction in the vpassing oft-the. platesonto the car door. For convenience inthedelaims, this'mov einent of the crevice-closing plate may be termedi-an' ir- -13egulan imovement in contradistinction to a movement in--which the plate is carried outwardly; with -the. longitudinal edges thereof retained in vertical position.

.The lower crevice-closing plate 41 is, actuatedin itsmovements. in,contact with the metallic'plate 26 secured to the side of the car. ,-Th1s last-mentioned crevice-closing plate has -diagonal/guide slots 54 through which extendmhe spacing lugs formed .on the brackets 25, and at oneend ofsaid creviceclosing plate a circular vopening. 55' is arranged, in which-an eccentric actuating disk 56.issit uated, said disk being siniilar in construction ,to the actuating; disk 43 previously described; and. having the non-circular portion-ofgits-stuhshaft projecting through the lower track, as at 46, for convenience in applying a wrench or other suitable tool thereto for actuating the same. With the creviceclosing plate provided with a series of diagonal guide slots, the plate is carriednpwardly so as to overlap the lower marginal portion of the car door when actuating said eccentric disk 56, the longitudinal edges of said plate being retained in horizontal po sition during such movement so that the entire upper edge of the same is brought into co'ntact with the door at the same instant, in contradistinction to the action of iczlhe crevice-closing plate at the side of the oor.

Provision is made for locking the creviceclosing plates in either of their two positions, and for this purpose the side creviceclosing plate is provided with two elongated key openings 57 58, while the plates 36, 38, which may be said to form a casing for the side crevice-closing plate has registering elongated openings 59, 60, respectively. In rear of the casing formed by said plates 36, 38, a recess 61 is formed in the car sill, for a urpose to presentl appear. When this si e crevice-closin p ate is moved into its receiving casing, t e key opening 58 in said plate is brought into registration with the registering openings 59, 60, in said casing, and a suitable key, such as shown at 62, 15 inserted through the three registering openings, said key havin an angular portion 63 at its inner end whic enters the recess 61 in the car sill. Upon turning said key one quarter of a complete revolution, the angular portion 63 is swung behind the casing and out of line with the registerin key openings, thus holding the crevice-c osing plate against movement. \Vith a view of preventingmanipulation of said key, the outer end of the same is rovided with an angular I ortion 64 whic 1 has a hole 65 formed t erein, and when swinging said keyjnto locking position, as shown in Fig. 11, said outer angular portion 61 is-swung against an outstanding lug 66 formed on the casing of the crevice-closin plate said lug having an opening 67 throng which and the opening 65 in the key, a seal 68 may be passed so that it will be necessary to break the seal before the key can be removed, it being apparent that so long as the key is held in the key openings in the crevice-closing plate and 1ts casing, said plate cannot be actuated. \Vhen it is desired to use the cur containing my improvements for transporting package or bulk freight, the creviceclosing plate will be locked in this position. thus reventing actuation of the same and guar ing against useless wear or mischievous destruction of the parts. When, however, the car is used for transporting grainand the crevice-closing plate moved outward to overlap the adjacent edge of the car door, the key opening 57 in said plate'is brought into registration with the registering opening 59, in the casing, and by msertmg the key through the three registering openings and manipulating the same, as described a seal may be passed through the key and the coiiperating lug so as to lock the crevice-closing plate in overlapping position and the door in closed position.

The lower or horizontal crevice-closing plate 41 is provided with an elongated key opening 69, and as this key opening is net'- erably at the extreme right hand end 0 said plate, a pair of register-in elongated key openings 70, 71 are provide in the plate 26 and a plate 119, secured to plate 34, said plate 26,having at its right hand end the outstanding flan e whereby the plate 119 is separated rom the body of the plate 26 so as to form a chamber for the reception of the right hand end of the lower or horizontal crevice-closing plate 11. \Vhen said crevice-closing plate is moved upwardly with a slight component longitudinal movement, due to the inclination of its guide slots 54, the right hand end edge of said plate is brought adjacent the registering openings 70, 71 in lates '26 and 119, respectively, and by inserting a key 72, similar to the key 62 a ove described, said key prevents receding movement of said plate. t is to be understood that key 72 is constructed with an angular inner end portion adapted to enter a. pocket in the car sill similar to recess 61 shown in Fi 11, and at its outer end it also has an angular portion, similar to the key 62, through which angular portion and a lug 7 3 on the plate 119 a seal 121 is passed, thus locking the lower or horizontal crevice-closing plate in position to close the crevice between the lower edge of the car door and the door sill. When said crevice-closing plate is moved downwardly out of contact with the car door, the key opening 69 in said plate is brought into registration with the pair of re 'stering openings 70, 71, and by inserting a ey in the registering openin s and mani u ating the same, as described, the plate will be locked in its lowermost position.

\Vhen the door is in closed position, its front face is flush with the inner face of the facing filate 3-1 at one side of the door opening, an' with the inner face of the vertical crevice-closing plate 36 at the opposite side of the opening, it being retained against outward movement by said facing plate 3-1 and crevice-closing plate 36. Where the door jamb is rabbeted, rubber or other suitabh cushion members 74 are provided against which the inner angles or corners of the doc] bear, thus making a tight joint and preveln rattling of the (1001'. By reason of the posi tion in which the door is held when closed it is necessary in opening the same to swing out one side of the door before it can b retracted from the pocket 35 formed at th other side of the door opening, and beforeit is possible to Swing out'th e'first mentioned side of the door the crevice-closing plates must be withdrawn from looking position. The means provided for -moving'the' door outwardly preparatory to slidin it on its tracks, comprises a vertical shaft 75 journaled to the door, as at 7 6, eachfe'nd of said shaft having an angular. ortion 77. The upper angular portion 77 0 said shaft has an upwardly extending. stud 78 and the'lower angular portion has a downwardly extending stud 79, each of said stiids terminating in an enlargement or head 80. Thee'nlargement or head 80 at the upper end of said shaft is removably secured to a hanger 81, which has a roller 82 adapted to travel on the upper track 17.

Secured to the 11 per end of the door near one side thereof is a bracket 83 through which is passed a bolt 84, said bolt having a nut 85 applied thereto and bearing against the underside of an outstanding portion 86 of said bracket. Said bolt is removably secured to a hanger 87 similar in construction to the hanger 81 and forms with said hanger a pair of upper hangers by means of which the door is suspended.

The lower stud 79 of the shaft 75 enters a slide block 88 which is movable len hwise on the lower track 18, said slide b ock having a T-shaped slot 89 which receives the stud and its enlargement or head, and in order to prevent accidental removement of said stud from said slide block, a plug 90 is secured in said slot by means of a pin 91. It is to be noted that the studs 78, 79 at oposite extremities of the shaft 75 are capaiile of rotation respectively in the hanger 81 and slide block 88, and in order to rock said shaft a handle 92 is provided, said handle being formed in two sections93, 94', the section 93 being rigidly secured to said'shaft while the section 94 is pivotally secured to said rigid section. By thus arranging the handle, the pivoted portion may assume a vertical position, as shown in full lines in Fig. 1, but when operating the shaft said pivoted portion of the handle is swung to the position shown in dotted lines in said figure so as to permit the shaft to be more conveniently manipulated.

95 represents a bracket secured to the lower end of the car in the vertical plane of the bracket 83 and it is secured to a slide block 96 adapted for movement on the lower track 18. The construction of said slide block and the manner of connecting said bracket thereto being similar to the construction of the corresponding upper bracket and its connection thereof to its c0- operating hanger. The offset portions at the upper and lower ends of the shaft 75 serve ascranks and the manipulation of said shaft by means of the handle 92 causes one ing 97 side of the door to swing outwardly with the studs 78, 79, as its pivotal center, but as hereinbefore stated this outward movement cannot be brought about until after the crevice-closing plates are moved into receding position. Vhen the door is manipulated it may be moved along the track so as to withdraw the opposite side marginal portion of the door from its receiving pocket 35 in the adjacent door jamb, and by reason of the inclination of the tracks 17, 18at points above and beneath the car door opening, the door may be brought into a plane permitting its being moved outside of the car.

\Vhen usin the car equipped with my improved car door for' transporting package or bulk freight, the car is loaded and unloaded through the car door opening, the crevice-closing plates being retained and preferably locked in receding position so that the door may be slid alon its tracks. \Vhen, however, the car is to he used for transporting grain it is intended that the door shall be retained in closed position and coopered or closed by the plates 40, 41, and for the purpose of loading the car an open is provided in the car door 19 near its upper end, while for unloading the car an opening 98 is provided in the car door near its lower .end. The opening97 may be termed a charging-openin while the opening 98 may be termed a c ischarge o )ening. On the exterior of the door above the opening 97 a Z-shaped bar 99 is secured in any suitable manner, a portion of said bar being spaced from the door to provide a receiving pocket for the free end of a gate or door 100 which is adapted to close said opening. Said gate or door is pivotally secured at 101 to the cranks 102 of a crank-shaft 103 journaled for rocking movement in suitable brackets 104 secured to the car door directly beneath the oiening 97. The-gate or door 100 is there ore hin ed to the car door beneath the opening 9 and by reason of its havin connection with the cranks, the free end thereof will be entered in the space provided between the Z-bar and the car door. One end of the crank-shaft is rovided with a laterally-disposed arm or ever 105 which has an opening through which is adapted to be passed a lug 106 extending outwardly from the car door, said lug having an opening therethrough, through which is passed a seal 107 for lockin the crank-shaft in the position shown in Fig. 1. In this position said shaft. is locked against rocking movement and the door consequently locked in closed position with its free end behind the Z-bar. In order to open said door it will be necessary to break and remove the seal which will permit the crank-shaft to be rocked, and when rocking the same to bring the arm or lever 105 in a depending position with the cranks directed downwardly,

the free end of the door will then be withdrawn from the space between the Z-bar 99 and the car door, after which it may be swung on the shaft into open position permitting the introduction of grain into the car through the charging opening in any suitable manner.

The discharge opening 98 at the lower end of the car door is closed by a vertically sliding gate or door 108 which has secured to its lower or marginal portion a Z-bar 109 forming a longitudinal space along the lower edge of the gate or door into which is adapted to fit that portion of the car door immediately beneath the opening 98. It may here be remarked that the car door is preferably a composite door constructed of wood and metal, the door being preferably faced with a sheet of metal 110, and the door openings 97, 98 being formed through said sheet of metal and through the wooden ortion of the door faced b said sheet. he gate or door 108 is mova 1e in a verticallydisposed space or pocket 111 formed between the wooden portion of the door and the metallic facin sheet, the wooden portion of the door being cut away for this purpose. Said gate or door 108 is therefore capable of being moved upwardly into said space or pocket when opening the same, and in order to manipulate said gate or door, a bar 112 is secured to its upper end which extends upwardly through a passage 113 extending from the upper end of the space or pocket 111 to the door opening 97. To the sill of the last-mentioned opening is pivotall secured an angular keeper 114 the upwardly extending arm 115 of whic is adapted to be engaged by a loop 116 which is pivotall secured to the upper end of the bar 112. aid bar has an inwardly directed lug 117 which is adapted to engage the underside of the keeper, as clearly shown .in Fig. 13, and thus prevent the upward movement of said bar and consequently the opening of the gate or door 108. In order to permit the opening of said ate or door it is necessary to disengage t e loop 116 from the keeper 114, after which the keeper may be swung into a position parallel with the inner face of the car door, as shown in dotted lines in Fi 14, thus disengaging said keeper from t e lug 117 on the actuating bar of said gate or door and permitting said bar to be elevated and the gate or door 108 to be drawn upwardly into the space or pocket 111 so as to open the discharge 0 ening 98. It is of course apparent that be ore opening the discharge openflcplu of this potent may be obtained for m cents ing it is necessary to open the'charging opening, as access cannot be had to the actuating bar 112 until after the door of the charging opening is swung into open posltion. By reason of this construction the seal of the door closing the charging opening guards against manipulation of the doors closing the charging and discharge openings without detection.

Although the door is preferably acomposite door as shown, constructed of wood and metal, any other construction of car door may be used, as it would clearly be within the skill of any mechanic versed in the art to modify my invention to fit the particular requirements of the door.

It is to be understood that various changes may be resorted to without departing from the spirit of this invention or sacrificing any advantages thereof.

Having thus described. my what I claim is,

1. Means for closing a crevice between a car door and the body of a car comprising guiding elements on the car adjacent the car door opening, a plate having uiding slots through which said guiding elements are passed and having also a circular opening, an eccentric disk fitting into said opening and supported on the car, and means for rotating said eccentric disk.

2. Crevice-closing mechanism for car doors comprising guiding elements adjacent a car door opening, a crevice-closing plate having diagonally-arranged ide slots through which said guiding e ements are passed and having also a circular opening near one end thereof, an eccentricallyjournaled disk fitting into said opening to move said plate into two different positions and means for locking said plate 1n one 0% its positions.

3. Crevice-closing mechanism for our doors comprising guiding elements adjacent a car door opening, a crevice-closing plate having diagonally-arranged uide slots through which said guiding eements are passed and having also a clrcular opening near one end thereof, an eccentricallyinvention,

journaled disk fitting into said opening to move said plate into two different positions, and means for locking said plate in both positions.

In testimony whereof I afiix my signature in presence of two witnesses.
